Top 20 Most Common Insects in Emilia-Romagna

The speckled wood (Pararge aegeria) prefers to live in damp, dark woodlands. Unlike other butterflies, it's more active in shadier habitats rather than sunny ones. Males often fight over a perch, spiraling up to the treetops until they determine a winner. These perches are where the males find passing females.

The southern green shield bug larvae molt five times before they reach their mature size. They are named for their unpleasant scent and are considered pests due to their preference for feeding on leguminous plants such as soybeans. Wasps and flies that parasitize the southern green shield bug are sometimes used as biological controls for its population.

The painted lady is a migratory butterfly that spends part of the year in Northern Africa and then migrates to Europe during the warmer months. Although the adults feed on nectar from flowers, the larvae feed on the leaves of nettles and thistles.

An orb-weaving species, wasp spider (Argiope bruennichi) spins large, beautiful webs that require an hour to create. The thick, zigzagging line in the middle of the web may serve to entrance and attract its prey. As its name suggests, it is capable of wrapping, biting, and injecting various species of wasp. Females consume the smaller males after copulation.

The meadow brown (Maniola jurtina) is similar to the Gatekeeper in the way that it rests with its wings open due to the "eye spots" on either end of its wings that ward off predators. While the color is a deep brown, the caterpillar form is a beautiful bright green with little, white hairs and a dark line leading down its back.

Unique for its black coloring with white spots, the white spotted rose beetle has spread across Europe and into Asia by hitching a ride on traded plants. It's a voracious eater that consumes many parts of plants in addition to pollen and nectar, so some label it as a garden pest.

Melitaea didyma is a medium-sized butterfly with a wingspan reaching 3.5 - 5 cm. The overside of the wings is a bright orange-brown with dark brown markings arranged in rows, which are quite variable in quantity and size. Sometimes the colour of the females is a duller orange, shaded with grey-green. The underside of the wings is chequered pale yellow and pale orange. Melitaea didyma has seasonal forms and sexual dimorphism.

The upperside forewings are a bright orange with a dark outside edge border and with eight or nine black spots. The hindwings are dark with an orange border. Some females also have a row of blue spots inside the orange border and are known as form caeruleopunctata. The undersides are patterned in a similar way but are paler. The black spots on the forewings are outlined in yellow and the dark colouring is replaced by a pale brownish grey. The hindwings are the same brown/grey colour with small black dots and a narrow orange border. The caterpillars (larvae) are usually green, but some have a purple stripe down the middle of the back and along each side.

Melanargia galathea has a wingspan of 1.8–2.2 in. In these medium-sized butterflies the upper side of the wings is decorated with white and gray-black or dark brown markings, but it is always gray-black or dark brown checkered in the basal and distal areas. The underside is similar to the upper side but the drawings is light gray or light brown. On the underside of the hindwings is present a row of gray eye spots. The males and the females are quite similar, except that some females may have a yellowish nuance on the underside of the wings. The larvae are a lime-green colour, with a dark green line running down the middle of their back. The caterpillars are about 3 cm long. They are green or yellow with some lighter and darker narrow longitudinal lines. The head is always light brown.

The Early Darter (Sympetrum fonscolombii) is a species of dragonfly in the family of the leaflets (Libellulidae), which belongs to the great dragonfly (Anisoptera).
